IMPROVEMENT IN CURTAIN-FIXTURES.

Specification forming part of Letters Patent No- 145,040, dated November25, 1873; application filed August 20, 1873.

To all whom it may concern:

Be it known that I, J oHN F. WoLLnNsAK, of Chicago, in the county ofCook and State of Illinois, have invented a new and ImprovedShade-Fixture; and I do hereby declare the following to be a full andexact description of the same, reference being had to the accompanyingdrawings'forming part of this specifica-v tion, in which Figure 1 is aperspective view of my improved shade-fixture as applied to a window.Fig. 2 is a perspective view of the bracket and reversible pawl, andFig. 3 is aperspective view of the roller.

Similar letters of reference in the accompanying drawings denote thesame parts.

My invention relates to improvements in reversible curtain-fixtures; andconsists, first, in the employment, in connection with a reversibleroller, of a reversible spring-locking pawl provided with two radialcord-ar1ns, for operating the pawl on either side of the window-frame,as hereinafter more fully set forth. My invention further consists inthe employment of a roller provided with a peripheral groove for theshade-cord and lugs, for the engagement of a spring-locking pawlprovided with two radial arms.

In the accompanying drawings, A is the bracket, east with flanges B, forthe passage of screws, by which it is secured to a window casing orframe, and with a socket, O, to receive the journal of the roller D. Thelatter is cast with a recess in one side to receive the end of the uppershade-roller, and with a pcripheral groove for the shade-cord, as shownin my patent of April 16, 1872. E E are square radial lugs, cast uponthe periphery of the roller, as shown, to act as stops against thespring-pawl F. The pawl is pivoted to the face of the bracket by ascrew, G, and is formed with three radial arms two, H H, upon one sideof the pivot for receiving the operatingcord, and one upon the oppositeside to form a head, J, against which the stops of the roller rest. Thehead is also formed with a lateral lug, K, to enter a recess, 1, in thebracket, for the purpose of limiting the movement of the pawl. M is aspring, coiled around the pivot of the pawl to hold the head of thelatter in contact with the roller. One end is fastened, in anyconvenient manner, to the bracket, and the other to the pawl, as will bereadily understoodl The operating cord is connected to the pawl by ashort wire link or eye-rod, N, for the purpose of preventing the cordfrom being caught in the bracket, and to insure its operation forreleasing the pawl from the roller.

If desired, the bracket may be constructed without the flange, andsecured to the side of the easin g by screws passing through its face.

By constructing the roller with the straight radial stops, it can beused either upon the right or left of the casing with equal effect; andby constructing the pawl with double arms for the operating cord, it mayalso be changed fromone side to the other, to correspond with theposition of the roller. The bracket may also be changed, if desired, orboth brackets made alike, and the pawl only removed.

By my invention, the fixtures are adapted JOHN F. VVOLLENSAK.
